Recording medium apparatus

Abstract

A disk control apparatus includes a shock sensor detecting a shock applied to a disk portion performing data reading and writing on a hard disk, and a shock log data generation manager creating shock log data concerning the detected shock, based on a predetermined shock determination threshold value relating to the level of the shock.

 a shock history data memory accumulating the created shock history data; 
 shock history data information external output means of outputting information on the accumulated shock history data at predetermining timing; and 
 place detecting means of detecting a place; 
 wherein the shock history data creating means writes information on the detected place into the shock history data. 
 
   
   
     2. A shock history data creating apparatus according to  claim 1 , further comprising control means of performing control relating to the data reading and/or writing based on a plurality of operation modes,
 wherein the shock level criterion is a criterion relating to a shock level determined for each of the operation modes. 
 
   
   
     3. A shock history data creating apparatus according to  claim 2 , further comprising operation mode detecting means of detecting the operation mode,
 wherein the shock history data creating means writes information on the detected operation mode into the shock history data. 
 
   
   
     4. A shock history data creating apparatus according to  claim 1 , further comprising reading/writing position detecting means of detecting a reading/writing position of the predetermined recording medium on which the data reading or writing is performed,
 wherein the shock history data creating means writes information on the detected reading/writing position into the shock history data. 
 
   
   
     5. A shock history data creating apparatus according to  claim 1 , further comprising time detecting means of detecting a time,
 wherein the shock history data creating means writes information on the detected time into the shock history data. 
 
   
   
     6. A shock history data creating apparatus according to  claim 1 , further comprising shock level criterion changing means of changing the shock level criterion in accordance with an external instruction. 
   
   
     7. A shock history data creating apparatus according to  claim 1 , wherein the shock level criterion is a criterion relating to a level of the shock determined for each of a plurality of predetermined directions. 
   
   
     8. A shock history data creating apparatus according to  claim 7 , wherein the shock history data creating means writes information on the predetermined direction in which the shock is applied into the shock history data. 
   
   
     9. A shock history data creating apparatus according to  claim 7 , wherein the predetermined recording medium is a hard disk,
 the data reading and writing means is a hard disk drive, 
 the shock level criterion is a threshold value corresponding to an upper limit of the level of the shock that the hard disk and the hard disk drive can endure, and 
 the threshold value determined with respect to a direction vertical to a surface of the hard disk is lower than the threshold value determined with respect to a direction parallel to the surface of the hard disk. 
 
   
   
     10. A shock history data creating apparatus according to  claim 1 , further comprising data reading and writing inhibiting means of inhibiting data reading and/or writing when the detected shock exceeds a predetermined limit. 
   
   
     11. A shock history data creating apparatus according to  claim 1 , further comprising:
 warning creating means of creating a warning relating to the detected shock based on the accumulated shock history data; and 
 warning external output means of outputting the created warning at predetermined timing. 
 
   
   
     12. A shock history data creating method comprising:
 a shock detecting step of detecting (a) a shock applied to data reading and writing means of performing data reading and/or writing on a predetermined recording medium, and/or (b) a shock applied to the predetermined recording medium; 
 a shock history data creating step of creating shock history data concerning the detected shock based on a predetermined shock level criterion relating to a level of the shock; 
 a shock history data accumulating step for accumulating the created shock history data; 
 an outputting step of outputting information on the accumulated shock history data at predetermining timing; and 
 a place detecting step of detecting a place; 
 wherein the shock history data creating step includes writing information on the detected place into the shock history data. 
 
   
   
     13. A computer readable medium including a program for causing a computer to execute the steps of:
 a shock detecting step of detecting (a) a shock applied to data reading and writing means of performing data reading and/or writing on a predetermined recording medium, and/or (b) a shock applied to the predetermined recording medium; 
 a shock history data creating step of creating shock history data concerning the detected shock based on a predetermined shock level criterion relating to a level of the shock; 
 a shock history data accumulating steo for accumulating the created shock history data; and 
 an outputting step of outputting information on the accumulated shock history data at predetermining timing; and 
 a place detecting step of detecting a place; 
 wherein the shock history data creating step includes writing information on the detected place into the shock history data.
